The brand of chews I give Gizmo are N-bone brand which are different then the nbone sold that are nylabones. They have dental chews that are vanilla and peppermint, and he also loves the teething rings that are pumpkin and sweet potato. They don't have the gelatin in them that the nbone nylabones have in them and are really healthy for your pup. They also have a tone of other types of chews to choose from, the 2 I listed are Gizmos favorites though :-) here is a link to their site
